Careful now, 'sled' is in its alpha stage. Heck, its name is a recursive acronym that means "sled likes eating data", so that should give you an indication of its state (I hope they come up with a new one once the software is stable). The project's goals are on point:
- don't make the user think. the interface should be obvious.
- don't surprise users with performance traps.
- don't wake up operators. bring reliability techniques from academia into real-world practice.
- don't use so much electricity. our data structures should play to modern hardware's strengths.
